Calls

Delta Chat supports one-to-one audio calls and video calls.

Calls are supported on Desktop, Ubuntu Touch, iOS and Android 8 and newer.

Place a call

• In a one-to-one chat, tap the 📞 call icon.

• This opens a small menu where you can choose whether to place an Audio Call or a Video Call.

Accept or reject a call

• When someone calls you, Delta Chat shows an incoming call screen or notification.

• Tap Accept to answer or Decline to reject the call.

During a call

• You can mute your microphone.

• You can enable or disable your camera.

• On mobile, you can switch between front and back cameras.

Depending on the device, you can also select the audio output or use picture-in-picture. On desktop, the call is using a dedicated window and you can continue using the main Delta Chat window as usual.

Missed calls and notifications

• If you do not answer, do not hear the ringing, or do not have your device at hand, the call appears as a missed call.

• Only your accepted contacts can make your device ring. Contact requests will appear as usual and will not ring.

• At Settings → Notifications → Calls, you can disable the special call ringing screen completely. If you do so, you will not be disturbed by any ringing notification, you can still pick up the call by tapping the incoming call message bubble in its chat.
